Physicists have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions could form an explanation for the elusive dark matter that ...

The cosmos has delivered a rare kind of fireworks display, and astronomers are racing to understand what it means. A strange double flash from a distant galaxy appears to show two neutron stars ...

The collision of two neutron stars around 130 million light-years from Earth, and the unique physics this merger created, may have shed new light on dark matter. Axions have never been directly ...

A double blast of dying stars may be the first observed case of a long-hypothesized, never proven “superkilonova.” Although astronomers are still searching for concrete answers, a study published in ...

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of millions of years, these stars progressively cool down, radiating heat into ...

"Our research establishes a strong link between quantum mechanics and astrophysics and provides a new perspective on the inner nature of neutron stars." When you purchase through links on our site, we ...

Astronomers may have discovered the first example of an explosive cosmic event called a "superkilonova," in the form of a gravitational wave signal detected on Aug. 18, 2025.

The LIGO/VIRGO/KAGRA collaboration searches the universe for gravitational waves produced by the mergers of black holes and neutron stars. It has now announced the detection of a signal indicating a ...
